· In case of inhalation : After inhalation of aerosols: damage to the affected mucous membranes.
· In case of skin contact : Severe burns with formation of scabs.
· In case of eye contact : Burns, corneal lesion.
· In case of ingestion : Severe pain (risk of perforation!), nausea, vomiting and diarrhea.
· Systemic effects : Mercury compounds have a cytotoxic and protoplasmatoxic effect. Intoxication symptoms: ACUTE: contact with eyes causes severe lesions. Swallowing and inhalation of dust damages mucous membranes of gastrointestinal and respiratory tract (metallic taste, nausea, vomiting, abdominal pain, bloody diarrhea, intestinal burns, glottal edema, aspiration pneumonia); drop in blood pressure, cardiac disrhythmia, circulatory collapse, and renal failure; chronic. CHRONIC: inflammation of the mouth with loss of teeth and mercurial line. The principal signs manifest themselves in the CNS (impaired speech, vision, hearing and sensitivity, loss of memory, irritability, hallucinations, delirium inter alia).
· Further data : The product should be handled with the care usual when dealing with chemicals.
· Ecotoxic effect : Quantitative data on the ecological effect of this product are not available.
· Biological effects : High aquatic toxicity. Harmful effect due to pH shift. Caustic even in diluted form. Endangers drinking water supplies if it enters in large quantities in soil and/or waters. Does not cause biological oxygen deficit.
